[0034] Figure 1 An escalator 10 is illustrated. In the subsequent description, it should become apparent that the present invention is applicable to other passenger conveyors, such as moving walkways. The escalator 10 generally includes a truss 12 extending between a lower landing 14 and an upper landing 16, the truss 12 being fixedly installed on site. A plurality of sequentially connected steps 18 are connected to a step chain 20 and travel through a closed loop path within the truss 12 along the guide rails fixed thereto, thereby forming a conveying section for carrying passengers. Pairs of handrails 22 include moving handrails 24. A drive machine 26 or drive system is typically positioned in a machine space 28 below the upper landing 16, or alternatively or additionally positioned in a machine space 28' below the lower landing 14. The drive machine 26 is configured to drive the steps 18 and / or handrails 24 through the step chain 20. The drive machine 26 operates to move the steps 18 in a selected direction at a desired speed under normal operating conditions.

[0035] The steps 18 make a 180 degree change of direction in a turning area 19 located below the lower landing 14 and the upper landing 16. The steps 18 are pivotally attached to a step chain 20 and follow the closed loop path of the step chain 20, running from one landing to another and back again.

[0036] The driving machine 26 includes a first driving component 32 such as a motor output sprocket, which can be connected to a driving motor 34 through, for example, a chain reduction assembly 36, which includes a second driving component 38 such as an output sprocket, which is driven by a driving chain 39 formed by, for example, an output chain. In some embodiments, the first driving component 32 is a driving component, and the second driving component 38 is a driven component.

[0037] As used herein, in various embodiments, the first drive component 32 and / or the second drive component 38 can be any type of rotating device, such as a sprocket, a rope, a pulley, a gear, a wheel, a cog, a pinion, etc. In various embodiments, the drive chain 39 can be configured as a chain, a belt, a cable, a belt, a band, a strip, or any other similar device that operatively connects two elements to provide a driving force from one element to another element. For example, the drive chain 39 can be any type of interconnecting component that extends between the first drive component 32 and the second drive component 38 and operatively connects the first drive component 32 and the second drive component 38. In some embodiments, as Figure 1 As shown in FIG. 1 , the first drive member 32 and the second drive member 38 may provide a chain reduction. For example, the diameter of the first drive member 32 may be approximately 75 mm (2.95 inches), while the diameter of the second drive member 38 may be approximately 750 mm (29.53 inches). For example, the chain reduction allows the sprockets to be replaced to change the speed for 50 or 60 Hz mains power applications or different step speeds. However, in other embodiments, the second drive member 38 may be substantially similar to the first drive member 32.

[0038] As noted, the first drive member 32 is driven by the drive motor 34 and is thus configured to drive the drive chain 39 and the second drive member 38. In some embodiments, the second drive member 38 may be an idler gear or similar device that is driven by the drive chain 39 through the operative connection between the first drive member 32 and the second drive member 38. The drive chain 39 travels around a loop set by the first drive member 32 and the second drive member 38, which may be referred to as a small loop hereinafter. The small loop is provided for driving a larger loop, which is composed of the step chain 20 and is driven by, for example, the output sprocket 40. Under normal operating conditions, based on the movement speed of the first drive member 32 as driven by the drive motor 34, the drive chain 39 and the step chain 20 may move in unison.

[0039] The escalator 10 also includes a controller 115 in electronic communication with the drive motor 34. As shown, the controller 115 can be positioned in the machine space 28 of the escalator 10 and is configured to control the operation of the escalator 10. For example, the controller 115 can provide a drive signal to the drive motor 34 to control the acceleration, deceleration, stop, etc. of the step 18 via the drive chain 39 and through the step chain 20. The controller 115 can be an electronic controller including a processor and an associated memory, the memory including computer executable instructions, which, when executed by the processor, cause the processor to perform a variety of operations. The processor can be, but is not limited to, a single processor or multi-processor system of any architecture in a variety of possible architectures, including field programmable gate arrays (FPGAs), central processing units (CPUs), application specific integrated circuits (ASICs), digital signal processors (DSPs), or graphics processing units (GPUs) hardware arranged in a homogeneous or heterogeneous manner. The memory can be, but is not limited to, random access memory (RAM), read-only memory (ROM), or other electronic, optical, magnetic, or any other computer-readable medium.

[0040] Although described herein as a specific escalator drive system and specific components, this is merely exemplary, and those skilled in the art will recognize that other escalator system configurations may operate with the invention disclosed herein.

[0041] One or more automatic step cleaning devices 50 may be configured in the escalator 10 according to application requirements to clean the steps. For example, they may be installed near one or more turning areas 19 of the step chain 20, such as in the machine space 28 of the upper station 16 and / or in the machine space 28' of the lower station 14. When the steps in the escalator 10 travel to such positions, they will usually turn, that is, the step treads will experience a state of flipping from top to bottom. It should be understood that for the purpose of description herein, the technical terms "up", "down", "right", "left", "front", "back", "vertical" and their derivatives should be associated with such as Figure 1 The invention is oriented in the embodiment of the present invention, however, the invention may assume various alternative orientations, except where expressly specified to the contrary.

[0042] As an example, in Figure 2 FIG. 4 specifically shows a general situation in which an automatic step cleaning device 50 is arranged in the machine space 28' of the lower station 14. Figure 2 As shown, the automatic step cleaning device 50 may include a base 51, a rotating shaft 52 and a cleaning member 53. Figure 2 The drawings of FIG. 1 do not show another optional cleaning member 55 and a bracket 58, but in the following Figures 3 to 5They are clearly shown in the .

[0043] The base 51 is used to support the rotating shaft 52. It can be installed near the steps in the flipped state, for example, fixed to the truss 12 or the work floor in the machine space 28' of the lower station 14, so that the cleaning member 53 provided on the rotating shaft 52 can be used to clean the steps passing through the rotating shaft 52.

[0044] Combined with reference Figure 3 As an example, the base 51 can be constructed with a bracket 511 and a bearing seat 512. According to actual application requirements, the bracket 511 can be installed in place at the desired position by using any feasible connection method such as a connector, welding, riveting, etc. The bearing seat 512 is fixedly connected to the bracket 511 and is used to support the rotating shaft 52, for example, Figure 3 It is schematically shown in the figure that the bearing seats 512 can be arranged at both ends of the rotating shaft 52 to play a bearing role for the latter.

[0045] The rotating shaft 52 can be made of steel, iron or other suitable materials, and can be arranged to be aligned with the running direction of the steps in the escalator 10 ( Figure 1 The driven component can be installed on the rotating shaft 52 and arranged in the transmission link of the drive chain 39, so that the rotating shaft 52 can be directly driven to rotate together when the drive motor 34 runs to provide power output. Figure 3 The figure shows that a sprocket 54 can be installed on the rotating shaft 52, and the sprocket 54 is meshed with a drive chain 39 configured as an endless chain, so that the rotating shaft 52 is driven to rotate synchronously with the circulation of the drive chain 39. In other words, the automatic step cleaning device 50 can be put into operation without the need for additional separate drive equipment, and can rotate synchronously with the drive chain 39 and the step chain 20.

[0046] The cleaning member 53 can be mounted on the rotating shaft 52 by means of key connection, for example. More specifically, the cleaning member 53 can be provided with a cleaning roller 531 with bristles 532, and the bristles 532 extend outward along the peripheral direction of the cleaning roller 531. When the cleaning roller 531 is mounted on the rotating shaft 52, the bristles 532 can be used to clean the steps that have been partially or completely turned over on the rotating shaft 52, so as to remove various possible objects to be cleaned located on the steps (such as the pedal area, the step frame, etc.), such as particles, dust, stains, cigarette butts, food or packaging debris, etc. For example, the length of the cleaning roller 531 can be set to be not less than the step pedal width (see Figure 1The brush 532 is preferably made of any suitable material such as a non-metallic material, such as nylon, etc., and the brush 532 can be arranged in one or more groups on the cleaning roller 531 as needed. When multiple groups of bristles are configured, not only can the cleaning effect be enhanced, but also the overall service life of the cleaning member can be extended.

[0047] In the automatic step cleaning device 50, by flexibly selecting and designing or adjusting some structural configurations, such as the installation positions of the base 51 and the rotating shaft 52, the diameter size of the cleaning roller 531, the length or arrangement layout of the bristles 532, etc., it is allowed to clean only one step at the moment or two adjacent steps at the same time. Figure 2 It is explained that the bristles 532 on the cleaning member 53 of the automatic step cleaning device 50 can be used to clean the pedal 181 of the step 18 and the pedal 181' of another adjacent step 18' respectively, which is conducive to improving the working efficiency of the automatic step cleaning device and enhancing the cleaning effect.

[0048] As used herein, in various embodiments, the rotating shaft 52 can be arranged to rotate synchronously with the step chain 20, and the rotating direction of the rotating shaft 52 is opposite to the rotating direction of the step chain 20, that is, the cleaning member and the cleaned step can rotate synchronously and in opposite directions. In this way, the force of the bristles of the cleaning member when contacting the step to be cleaned can be effectively increased, thereby enhancing the cleaning processing ability and obtaining a better cleaning effect.

[0049] Continue to refer Figure 3 , Figure 4 and Figure 5 , the automatic step cleaning device 50 may be optionally equipped with a container 57 to contain the cleaning material generated after the step cleaning operation by the cleaning member, so as to facilitate subsequent processing of such cleaning material, such as regular or irregular cleaning of such cleaning material by staff. As used herein, in various embodiments, the container 57 may be arranged directly below the rotating shaft 52 to facilitate storage of the above-mentioned cleaning material. Figure 4 By way of example, the receiving member 57 can be constructed as a relatively simple but practical substantially plate-shaped structure. Of course, it is also permitted by the present invention to configure it into other suitable structures as required.

[0050] As used herein, in various embodiments, an additional cleaning member 55 may be provided in the automatic step cleaning device 50 so as to be used exclusively to clean the cleaning member 53, so that the cleaning member 53 itself can still have a good cleanliness after continuous use, thereby being able to better complete the cleaning operation of the step. Figure 3 In the example, it is shown that the cleaning member 55 can be arranged in parallel with the cleaning member 53 and configured to have comb teeth 56, which face the bristles 532 of the cleaning member 53 and can contact the bristles when the rotating shaft 52 rotates, so that cleaning materials that may stick to the bristles 532 can be cleaned off from the bristles 532. The cleaning member 55 can be detachably mounted on the receiving member 57, for example, by means of one or more brackets 58 and connecting members 60 (such as screws, screws, etc.). When in use, the cleaning materials cleaned off from the bristles 532 of the cleaning member 53 by the comb teeth 56 of the cleaning member 55 will fall into the receiving member 57, and these cleaning materials can then be removed and disposed of, for example, by staff.

[0051] The specific structure and arrangement of the comb teeth 56 on the cleaning member 55 can be designed as required, as long as the above-discussed cleaning effect on the bristles 532 of the cleaning member 53 can be achieved. For example, the cleaning member 55 can be arranged so that the comb teeth 56 are perpendicular to the vertical direction ( Figure 1 The brush 532 is arranged in an inclined manner (for example, in the Z direction of the brush) (for example, 20°, 30°, 40°, 60°, 70° or any other inclination angle required for a specific application), and the tip of each comb tooth 56 facing outward is closer to the rotating shaft 52 than its root, which will help the cleaning materials cleaned out from the bristles 532 to fall into the position between the cleaning member 53 and the cleaning member 55 when they are separated, that is, the cleaning member 55 will properly shield them to avoid spreading outward, so as to facilitate the collection of these cleaning materials. For another example, the length of the corresponding part of the comb teeth 56 on the cleaning member 55 can be flexibly configured, for example, it can usually be set to be not less than the length of the cleaning roller 531, so that the cleaning member 53 can clean the cleaning roller 531 within the entire length range every time it works, thereby improving work efficiency.

[0052] As used herein, in various embodiments, the cleaning member 55 can be arranged on the other side of the rotating shaft 52 relative to the steps 18 and 18', which facilitates the cleaning member 53 to clean the steps on one side thereof, while the cleaning member 55 cleans itself on the other side, thereby completely realizing the reverse operation of the cleaning member 55 first actively cleaning and then passively being cleaned, which is completely not considered and proposed in the prior art. The solution of the present invention innovatively provides a cleaning operation for the cleaning member itself for cleaning the steps, thereby being able to improve the step cleaning processing capacity of the passenger conveyor to a higher degree and more permanently.

[0053] refer to Figure 2 and Figure 5In the automatic step cleaning device 50, a shielding member 59 may be additionally installed between the drive motor 34 and the rotating shaft 52, so as to at least partially shield the cleaning member 53 and the cleaning member 55 (if any), thereby reducing or eliminating the impact of the cleaning material generated by the automatic step cleaning device 50 during the cleaning operation on the on-site equipment such as the drive motor 34. As an example, the shielding member 59 may be configured in a plate shape or other suitable shape. As used herein, in various embodiments, the shielding member 59 may be connected to the truss 12 of the escalator and / or the aforementioned receiving member 57, which can be achieved using any feasible connection method such as a connector 70 (such as bolts, screws, etc.), welding, riveting, etc.

[0054] In the foregoing, exemplary explanations have been given of the specific structural composition and other aspects of the automatic step cleaning device 50, and in the accompanying drawings, for example, the rotating shaft 52, the cleaning member 53, the cleaning member 55, the containing member 57, the shielding member 59, etc. are schematically displayed. However, it should be noted that the present invention is not limited to these components and their structural configurations. For example, in one or some embodiments, both the cleaning member 53 and the cleaning member 55 can be used alone or in combination with any suitable device such as a vacuum cleaner, a hair dryer, a dust-absorbing tape, etc., as long as they can be used to achieve the purpose of cleaning the steps of the passenger conveyor.

[0055] The above is only an example to explain in detail the automatic step cleaning device for passenger conveyors and passenger conveyors according to the present invention. These examples are only used to illustrate the principles and implementation methods of the present invention, but not to limit the present invention. Without departing from the scope of the present invention, those skilled in the art can also make various modifications and improvements. Therefore, all equivalent technical solutions should belong to the scope of the present invention and be defined by the claims of the present invention.
